FREDRI OK FIEDERLEIN, OF NEW YORK, N. Y.

MASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 244,576, dated July 19, 1881.

Application filed February 2, 1881. (No model.) i

To all whom at may concern H v Be it known that I, FREDRICK FIEDERLEIN, of the city, county, and State of New York,

have invented certain new and useful Improve,

ments in Mashing-Machines, of which the following is a specification.

This invention has reference to improvements in rotating mashing-machines, by which a more uniform mixing of the mash is obtained and it consists of the combination, with a system of vertically-rotating stirrer-arms supported on horizontally-revolvin g arms, of a vertical auxiliary shaft having horizontal stirrer-arms, and of mechanism whereby the latter are rotated while turning with the main driving-shaft, so as to throw the mash toward the circumference of the tub and into the path of the vertically-revolvin g stirrers.

In the accompanying drawings, Figure 1 represents a side elevation of my improved mashing-machine, partly in section through the mash-tub. Fig. 2 is atop view of the auxiliary stirring mechanism; and Fig. 3 is a verticaltransverse section on line no 00, Fig. 2.

Similar letters of reference indicate corresponding parts.

A in the drawings represents the main stirrer-arms, which are secured in the'usual manner to horizontal revolving shafts A, which are supported-in bearings of hangers A suspended from fixed horizontal arms A of the the central vertical driving-shaft, B. The horizontal shafts A are actuated by a central bevel-gear wheel, a, of the driving-shaft B, which meshes with bevel-pinions b b at the inner ends of the revolving shafts A, so as to be vertically rotated while being simultaneously moved around the driving-shaft B. The driving-shaft B is supported in the usual manner on a central step-bearin g of the mash-tub.

To the central driving-shaft, B, are applied, at right angles to the main supporting-arms A shorter arms 0, which carry in bearings at their outer endsan auxiliary vertical shaft, 0. To the shaft 0 are applied horizontal stirrerarms 0 which are alternately placed at right angles to each other. A pinion, d, is keyed to the auxiliary shaft D, and arranged to mesh with a gear-wheel, e, which is keyed permanently to the step-bearing'of the main drivingshaft 0, so that the auxiliary driving-shaft, in following the motion of the main driving-shaft,

simultaneously revolves the horizontal stirrerarms 0 The auxiliary shaft and arms agitate thereby that body of the mash at the central part of the tub immediately around the main driving-shaft, and throw it toward the circumference of the tub and into the path of the vertically-revolving stirrers A, so as to produce thereby, in a higher degree than heretofore, the uniform and reliable working up of the mash. 1

I am aware that mashing-tuns have been constructed with stirrers which revolve about their own axes and also revolve around the vertical central shaft. Such a contrivance I do not claim. I have introduced between the vertically-turnin g stirrers horizontally-turnin g blades, which serve the twofold purpose of stirrers and clearers. These blades,when combined with the vertical stirrers, operate to produce a uniform distribution of the mash upon the bottom of the tub, and they prevent the banking up of the material about the central shaft.

I am also aware that mashing-tans have been constructed with a straight horizontal shaft carrying vertically revolving stirrerarms, and a vertical shaft carrying horizontal arms rotating in close proximity to the central driving-shaft, and therefore I make no claim, broadly, to such a combination of stirrerarms.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a mash-tun wherein the vertical drivin g-shaft B is stepped inside of the tub, stirrers A, revolving in a vertical plane, in combination with one or more centrifugal interuary, 1881.
